The STM: from the CAM to the Opus

Radio-Canada’s archives look at the trip from the CAM to the Opus card: in 1980 an adult CAM cost $16.

(Incidentally, why is it that francophone media write OPUS and BIXI when these are not acronyms, as CAM was – i.e. Carte Autobus-Métro – ?)

(Update: I see I’ve asked this before and the reply is “branding” of course. I also see AZUR sometimes.)
